Pretty cool stuff :)

"The speed of light in free space is 186,282 miles per second, which until now was thought to be a constant. While light slows down when passing through water or glass it returns to the speed of light when it comes out the other side. In this experiment the speed of a photon remains slightly slower."

"Complicated? Oh yes. Which is why the researchers say it might help to think of a bicycle race. The peloton - the main bunch of riders - may be moving at a constant speed. But within the bunch an individual rider may moving more slowly, dropping back for a rest or a drink. Meanwhile other riders in the bunch are moving faster to get to the front.
The bunch is a beam of light, travelling at - yes - the speed of light. The riders are photons, travelling at their individual speeds. "
